Objectives

Target Audience: This workshop will be taught at a beginner level and is open to anyone interested in learning about or improving their knowledge of plant terminology and the characteristics of common plant families, and becoming competent at plant keying using the Jepson Manual and online resources. Those just entering the world of plant identification will benefit from learning the diagnostic characteristics of the most important plant families in California. Those with prior plant identification experience will be able to refresh their skills and increase their proficiency with more difficult groups such as the Poaceae (grasses) and Asteraceae (sunflowers). Emphasis will be placed on common groups of plants in Northern California; however, information learned in this class will be readily applicable throughout California and the world.

Full Description: This is a 3-day introductory workshop. We will begin by teaching basic plant morphology with a focus on the structures necessary for plant ID. Participants will learn the specialized terminology necessary to identify plants in 15 common California plant families. These families contain more than 5000 taxa, which account for more than 70% of the plant diversity in California. Learning the characteristics of these plant families will reduce the amount of time required to key down to the species level. We will utilize live material and taxonomic keys to better understand morphology in each family. Scientific names, along with common names, will be used throughout the workshop. The class will include 2 days of classroom presentations and exercises and one full day in the field. Common native families, genera, and species will be covered, including species in conifer forest, oak woodland, montane chaparral, and meadows.

At the end of the workshop students can test their newly acquired knowledge by participating in an optional plant families identification game. A certificate of completion is given at the end of the course.

Participants will learn:

  • Basic plant morphology terminology
  • How to recognize 15 families of vascular plants encompassing 70% of the plant diversity in California
  • How to identify some common tree, shrub, and herbaceous species by sight
  • Tips for remembering the differences between similar plant families and species
  • How to use dichotomous keys for plant identification including The Jepson Manual, 2nd Edition
  • Additional resources available to help identify plants

The following plant families will be covered: Apiaceae (parsley), Asteraceae (sunflower), Brassicaceae (mustard), Caryophyllaceae (pink), Cyperaceae (sedge), Ericaceae (heather), Fabaceae (pea), Lamiaceae (mint), Onagraceae (evening primrose), Orobanchaceae (broomrape), Poaceae (grass), Plantaginaceae (plantain), Polemoniaceae (phlox), Polygonaceae (buckwheat), Rosaceae (rose).
